The film was produced by Will Ferrell and directed by Molly Gordon and Nick Lieberman. It was also written and produced by Ben Platt and Noah Galvin. Theater Camp stars Molly Gordon, Ben Platt, Noah Galvin, Jimmy Tatro, Patti Harrison, Ayo Edebiri and Amy Sedaris.

When the beloved founder of a run-down theater camp in upstate New York falls into a coma, the eccentric staff must band together with the founder's crypto-bro son to keep the camp afloat.

Theater Camp is based on a short film that Platt, Galvin, Lieberman, and Gordon made in 2020.
